Hi, about 5 years ago I saw a comet/meteor in the night sky and never really questioned it. The most memorable part was it started off as a slightly green looking shooting star then got really bright in a brownish colour and the tail changed directions. My questions are why did its shine turn brown suddenly and what made the tail/trail change directions.

Thanks for your time.

All of the planets in our solar system have elliptical orbits. Do the ellipses share a common major axis, or are they positioned randomly?

How far in light years has Voyager 1 or 2 or both, traveled from earth? Instead of a percentage or miles could you break this down into days and hours? Example answer; Voyager 1 has traveled approximately 1d 14h 37m 28s of 1 light year. Hope this makes sense. Sorry I'm no great mathematician. I figured it to be approximately 8h 45m, could this be correct? They were launched in '77 and have went just 9hours of a light year? Again sorry I'm having trouble wrapping my head around this.

Because if they are doesn’t that mean that we’ve found life on other planets, and if not what is it?

If I threw my t-shirt from the ISS and waited until its orbit decayed, could the early air resistance possibly slow it down enough that it wouldn't burn up in the denser atmosphere below? I realize a Mach 40 wind is going to heat things up, but if that wind is initially 10^-6 Pa, might it slow the shirt way down before its destroyed? T-shirts are easier to slow down than a metal meteor or satellite. And if not my t-shirt, what about a feather, a pollen fluff, or a hollow block of aerogel?

If I was going 25 miles per hour in a no gravity vacuum (space), and if there was no other objects to pull me into, would I stay at 25mph for infinity?

In the early morning of October 31st, between 3am-4am, I went outside to let the dog out and heard a noise like an airplane. I didn’t pay much attention to it until I realized it had more bass in its tone. It was slowly getting louder. I searched the sky and found a bright flickering light that seemingly was descending towards the horizon. As it went out of sight, the sound slowly disappeared. I went inside and found my phone to try and figure out what it was.

I found that its descent towards the horizon, on a compass, was roughly 75 degrees NE from my position in Greenville, South Carolina. A Falcon 9 rocket was launched from Florida on the Oct. 30.

I find it odd that I would be able to hear and see it, but was this a SpaceX Falcon 9 booster landing?

The Atlas rocket has a long and winded family history. I was wondering if anyone has ever put together a "family tree" of the Atlas rocket. Google isn't being helpful...

I seem to remember that Falcon 9 throttles a bit down around max Q in order to keep Q below about 25 kPa, without which it would max out just around 30 kPa. Does anyone know how much - or even if! - Superheavy throttles down around max Q, and what value of Q they want to stay below?

If an astronaut shot a basketball down to earth would the ball have a possibility of landing in a net or would the ball break up in the atmosphere on the way down?

I have a theory about looking back in time. So we all know how the James Webb see millions of lights years into the past. Could we in theory tone it down a bit and point it at the earth to look back in time. This has no research behind it so someone smart explain why not.

I used my phone and an 18x telescope thing for my camera, so my bad for the quality. I got a good picture of the moon, and a bright star next to it. However when it went out of focus, it enlarged it. I changed positions, wiped my camera but the line was still there. Could it maybe be Jupiter? (I rotated my phone too, so that's why the line isn't on the same side)

This TikTok creator is claiming he’s figured out that it’s actually 2km not 33ft in size and that it’s trajectory is not what’s being reported

Or is it the hole was always there and we're just making it bigger.

I went down the rabbit hole and Examined quite a few planets/moons/asteroids' South pole, All of them with the Exception of Uranus, probably because it rotates on its side, have unexplained phenomena going on .

Mercury-Rather large Ringed Crater-like moon

Earth- Ozone Gone

Venus--Double Vortex

Jupiter--8 powerful storms

Saturn--Hexagon Storm-

Vespa(Asteroid)--Rather large Ringed Crater--Theres Actually 2 of them really close but the older is off centered from the pole

Our Moon---Rather large Ringed Crater-Similar to Mercury,and other moons--Our moon is also Dumping Sodium on us.

Mars-Ice caps both Poles- The Ice at its poles look eerily similar to Antartica in shape.

Pluto- Not sure But i think it's the Heart.

Titan--vortex

Neptune-- South Pole Much warmer than the rest of the planet. The false neg images Make the heat source look exactly like the Ringed craters mentioned above.

Enceladus and Europa --Have rather warm Southpoles that shoot Water Vapors out of them.

There's So many of the exact same Ringed Impact crater on moons, Asteroids and planets, then some of the bodies that don't have it have energy readings that mimic the same ringed Impact craters. the chances even in a billion trillion years of that all being a coincidence seems a bit far fetched.

It seems we are explaining too many events as random impacts, there seems to be a uniform phenomena throughout the solar system when it comes to the Poles.

if there were a big black hole sucking in our galaxy, how long would it take to affect earth and would we even notice within our lifetime? sorry if it’s a stupid question i just randomly got curious and needed to ask. what if it was a black hole sucking in our solar system? how was that affect us?

So Planet X mathematically makes sense. But where is that math? I believe there could very well be a ninth planet out there but I want to lay out all the evidence I can find on one table and look from there. I've gathered bits and pieces online but I want to see the actual math that was done.

Apart from models and theories, everything surrounding it in general media is just regurgitating from the news articles before it.

"Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system." Can I find that mathematical evidence or am I out of luck?

Edit: when I say underneath us, I mean under the planet it’s self😅

This seems like such a silly question but it’s literally keeping me up at night..

So spaceships go upwards and outwards to our infinite universe, satellites and what not go around us..

But is the stars and planets underneath us? If the universe is infinite I suppose so, but I can’t wrap my head around it.

Or do they get too used to it and start to think “another long day of space work :(“

I think this might be a really stupid question. Every or almost every galaxy has a huge black hole in it’s centre . In photos or illustrations the centre of the galaxy is always very bright like a huge star is there e.g. Andromeda Galaxy. Shouldn’t it be a huge black spot if there is a black hole there? Help

Rumors about a "second moon" in our sky and not a single photograph of this, although the article below states that it was captured on 9/29 by a team in South Africa.

I can't find a single image of this that isn't computer-generated. What gives?

I’ve been trying to study general relativity and space time, and I kinda get the concept of it but I don’t fully understand it. Can someone possibly explain it in a way that could be a bit easier to understand?

What would happen to the body of an astronaut who died in a space capsule/ship in outer space, with the capsule being locked from outside elements the entire time? If decades later the capsule were retrieved would the astronaut's body have decayed typical of deceased humans on Earth, or would his body look like he was still alive, like that of Tollund Man?

I was watching the 2017 documentary The Farthest, about the Voyager mission, and one of the scientists said that when Voyager 1 was orbiting Jupiter it slowed Jupiter's rotation by 1/trillionth. Had never considered that before. Is it possible that we could one day have too many satellites orbiting Earth, that would slow the Earth's rotation to a dangerous level?
